This extension offers free integration with the iWish.be universal wishlist site.
Installing this plugin automatically adds the iWish.be button to each product page on your store, allowing users to add your products to their own wishlists with just a single click. Obviously, other iWish.be users wanting to purchase the product as a gift are directed back to your store.
Configuration options for the iWish button are available in the Admin Panel (System -> Configuration). Note that this plugin by default includes jQuery on your product page. You can disable this in the plugin's settings.
